How many moles is 2 water molecules?
One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many molecules are in 2.0 moles of Fe(NO3)2?
The number of molecules is 12,044280.10e23.
How many molecules are present in 3 moles of methanal?
The reaction is :- 2C2H6 + 7O2 ----------> 4CO2 + 6H2O When one mole ethane is combusted 7/2 moles of oxygen are used. When 3 moles of ethane are combusted 3 x 7/2 moles of oxygen used. No. of oxygen molecules consumed =6.022 x 1023 x7/2= 21.077 x 1023=2.107 x 1024 molecules.
Does 10o2 plus 10H2 make 20 moles of water?
No, this would make 5 moles. This is because water is H2O. This means that for each oxygen molecule used, there will be 2 hydrogen molecules used. In the given equation Only 5 moles of oxygen could be used to pair with all 10 moles of hydrogen, therefore giving you an excess of 5 oxygen molecules.
How many moles of Hydrogen are in 2 moles of H2O?
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
How many moles is 2 water molecules?
One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O
How many molecules are in 2.0 moles of Fe(NO3)2?
The number of molecules is 12,044280.10e23.
How many molecules of water are produced if 2.0g of sodium sulfate are produced in the above reactionH2SO4+2NaOH=H2O+Na2SO4?
The reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.
How many molecules of ammonia can be formed from the reaction of 2 molecules of Nitrogen gas and 6 molecules of hydrogen gas?
The chemical equation is N2 + 3H2 -> 2NH3 So reacting 2 moles of N2 will produce 4 moles ammonia.
How many atoms and are there in 36g of water?
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
If you have 2 tons of water how many moles of water do you have?
yes
How many moles of water vapor can be produced from 2 moles of ammonia?
6 moles COULD be produced
How many molecules are present in 3 moles of methanal?
The reaction is :- 2C2H6 + 7O2 ----------> 4CO2 + 6H2O When one mole ethane is combusted 7/2 moles of oxygen are used. When 3 moles of ethane are combusted 3 x 7/2 moles of oxygen used. No. of oxygen molecules consumed =6.022 x 1023 x7/2= 21.077 x 1023=2.107 x 1024 molecules.
calculate the number of moles in H2 molecules in 4g H2?
2 moles.
